About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X200-75S
Late design changes rarely force a re-order here: the MAJ40X200-75S accepts up to 75 mm of on-site trim to its extend stroke through the external stop screw, inside the 200 mm base stroke. Push force at 0.5 MPa is 628.3 N on a supply of 0.15-1.0 MPa (22-145 psi).
For sizing, treat about 377 N as the practical continuous push at 0.5 MPa rather than the full 628 N rating. The riveted round body - stainless barrel, hard-chrome 16 mm rod, aluminium-alloy covers - stays sealed and compact thanks to the rolled-on construction, and the fixed bumper pad only decelerates the stroke end; adjustable cushioning lives in the MACJ family instead.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X200-75S Is Used
Machine-rebuild slotting
Retrofitting an older milling machine's part ejector, the 75 mm window lets the fitter match a legacy stroke without re-ordering the cylinder.
Layer-clamp approach
A low-cost layer clamp on a small palletiser pulls 528 N at 0.5 MPa to hold slip sheets through the 200 mm approach move.
Glue-head standoff
Setting the gap between a glue nozzle and corrugated board is done at commissioning with the stop screw, locking repeatability across shifts.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X200-75S the Right Cylinder?
The nearest step down is the 32 mm bore at 402 N push / 346 N pull at 0.5 MPa, so pick it if your load needs under about 240 N; nothing in the MA range exceeds 40 mm, whose 628 N push tops the series. The air port for this bore is 1/8".
The -75 stop screw sets the extend position but acts purely as an end stop - with pressure removed the rod drifts freely, so never rely on it to park a load. FA flange or LB foot mounting, I or Y knuckles on the rod, and for this 200 mm stroke keep side forces off the 16 mm rod or add external guiding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X200-75S FAQ
At 0.5 MPa: 628.3 N push, 527.8 N pull. At 0.7 MPa: 879.6 N push, 738.9 N pull. Maximum theoretical force is 128.1 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, extend-stroke trim up to 75 mm.
Pick the FA flange for face mounting or the LB foot for base fixing; I and Y rod knuckles handle pivoting loads. The adjustable-stroke version does not carry the SDB double-rod or back-cover variants. The port size for this 40 mm bore is 1/8" and the rod thread is M12x1.25.
